City Knife

Beaverton, Ore.-based Nike’s City Knife was designed with the modern traveler in mind. If you run out of space in your carry-on bag, just fold the shoe and shove one in each pocket. Nike says the shoe’s collapsible design was inspired by “the intuitive, folding nature of the grocery bag—totally functional, yet space mindful.” The shoe retails for $90.
